Numerical Simulation of a Liquid Jet Atomization and Break-Up Using ANSYS-CFX 12.0
… to evaluate the accuracy of the numerical model. The CFD code ANSYS-CFX 12.0 was used to carry out the steady state analysis at different time scales. A comparison between the atomization characteristics of a pressure jet atomizer and an air-blast atomizer is shown. By employing a …

The Collisional Evolution of Orbital Debris in Geopotential Wells and Disposal Orbits
… in the selected regimes using a low velocity breakup model derived from the NASA EVOLVE breakup model. The simulations described in this thesis consider a set of perturbations including the geopotential, solar and lunar gravity, and solar radiation pressure forces. This thesis is based on a …

Modeling of droplet evaporation, flash-boiling, and mixture preparation in internal combustion engines
… engine technology. This study examines numerical models essential to the simulation of mixture preparation, a vital process that determines the combustion outcome. Combustion models are also developed for compression-ignition and spark-ignition engines, and are used to simulate the advanced engine …

Machine Learning Methods for Hypervelocity Fragment Flyout Characterization
<p>Resulting from breakup events, such as collisions and explosions, hypervelocity fragments create potential hazards for both terrestrial and on-orbit environments, such as terrestrial weapons explosions and satellite breakup events, respectively. To avoid unnecessary damage, an accurate …
